Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Effects of unsupervised exercise training on functional capacity and quality of life in patients with heart failure chronic
No full textIntroduction: Patients with chronic heart failure often have limiting symptoms such as breathlessness, fatigue and effort intolerance that impair substantially the functional capacity and quality of life. It is known that physical exercise is an important adjuvant treatment of heart failure. When performed supervised, offers many benefits, among them improved functional capacity and quality of life. On the other hand, little is known about these effects when performed in a unsupervised manner. Objectives: To evaluate the impact of a program of unsupervised exercise on the quality of life and functional capacity of patients with chronic heart failure, and assess adherence to the proposed exercise. Methods: Using a controlled clinical trial randomized into two groups, 22 patients with heart failure, who attended the outpatient Heart Failure, Hospital das Clinicas, Federal University of Goias, aged between 18 and 85 years, both sexes, class II or III and of any origin. The GT-training group (n = 13) were walking on a unsupervised for 10 weeks and educational workshop. The control group-CG (n = 9) received only educational workshop. Both groups underwent assessment of functional test through the six-minute walk (6MWT) and the assessment of quality of life using the SF-36, pre and post intervention. Results: The average age of TG was 62.1 ± 11.7 years and the CG was 65.9 ± 11.5 years. Both have increased the distance walked during the six-minute walk, the GT grew 64.1 m (p = 0.004) and GC increased 29.1 m (p = 0.03). Regarding quality of life, the TG showed improvement in six areas of the SF-36: physical functioning (p = 0.003), physical (p = 0.01), pain (p = 0.03), Social (p = 0.02), emotional role (p = 0.02) and mental health (p = 0.003). The GC showed improvement only in the mental health domain (p = 0.03). The adherence of the GT was 97% Conclusion: The unsupervised exercise was effective in improving functional capacity and quality of life in patients with chronic heart failure. The exercise adherence proposed was satisfactory.Introdução: Os pacientes com insuficiência cardíaca crônica apresentam frequentemente sintomas limitantes, como dispneia, fadiga e intolerância aos esforços, que comprometem substancialmente a capacidade funcional e a qualidade de vida. Sabe-se que o exercício físico é um importante coadjuvante do tratamento da insuficiência cardíaca. Quando esse é realizado de forma supervisionada, oferece muitos benefícios, dentre eles melhora da capacidade funcional e da qualidade de vida; por outro lado, pouco se sabe a respeito desses efeitos quando realizado de forma não-supervisionada. Objetivos: Avaliar o impacto de um programa de exercício físico não-supervisionado na qualidade de vida e na capacidade funcional de pacientes portadores de insuficiência cardíaca crônica, assim como avaliar a aderência ao exercício proposto. Métodos: Através de um ensaio clínico controlado, foram randomizados em dois grupos 22 pacientes com insuficiência cardíaca, atendidos no ambulatório de Insuficiência Cardíaca do Hospital das Clínicas da Universidade Federal de Goiás, idade entre 18 e 85 anos, ambos os sexos, classe funcional II ou III e de qualquer etiologia. O grupo treinamento-GT (n=13) realizou caminhadas de forma não-supervisionada por 10 semanas e oficina educacional. O grupo controle-GC (n=9) recebeu somente oficina educacional. Ambos os grupos foram submetidos à avaliação de capacidade funcional através do teste de caminhada de seis minutos (TC6) e à avaliação da qualidade de vida através do questionário SF-36, pré e pós intervenção. Resultados: A média de idade do GT foi de 62,1 ± 11,7 anos e no GC de 65,9 ±11,5 anos. Ambos aumentaram a distância percorrida no teste de caminhada de seis minutos; o GT aumentou 64,1m (p=0,004) e o GC aumentou 29,1m (p=0,03). Em relação à qualidade de vida, o GT apresentou melhora em seis domínios do questionário SF-36: capacidade funcional (p=0,003), aspecto físico (p=0,01), dor (p=0,03), aspecto social (p=0,02), aspecto emocional (p=0,02) e saúde mental (p=0,003). O GC apresentou melhora somente no domínio saúde mental (p=0,03). A aderência do GT foi de 97% Conclusão: O exercício não-supervisionado foi efetivo para a melhora da capacidade funcional e da qualidade de vida em pacientes com insuficiência cardíaca crônica. O exercício físico proposto apresentou aderência satisfatóri
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
